GREENWALD, OF DETROIT, MICHIGAN, ASSIGNOR T0 THOMAS 0. WHITE- HEAD, OF DETROIT, MICHIGAN BRINE TANK Application filed May 24, 1926. Serial No. 111,460.

This invention relates generally to brine tanks designed for use in refrigerating apparatus of the domestic type and consists of certain novel features of construction, combinations and arrangements of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a front elevationof a brine tank embodying my invention with the cover removed.

Figure 2 is a top plan view thereof.

Figure 3 is a vertical sectional view taken on the line 83 of Figure 1.

Figure 4 is a top plan. View of the cover.

Figure 5 is a transverse sectional view taken on the line 5-5 of Figure 4.

Figure 6 is an edge elevation of the cover shown in Figure 4.

Referring now to the drawings, 1 is a chamber for brine or other suitable liquids having a low freezing point, and 2 is a chamber for the molds or trays in which ice may be formed for table or other use. As shown, the brine chamber 1 is inverted U-shape in form and includes a hollow substantially rectangular shaped body 1 and a pair of laterally spaced substantially vertically dis-' posed hollow legs 3 depending from the lower wall 3 of said body. Preferably the body 1 has an open top and has openings 2 in its lower wall 3 at opposite ends thereof while the legs 3 have open upper ends registering with the openings 2' and have closed. lower ends 3 adapted to rest upon a suitable support (not shown) for the brine tank. The inner side walls 2" of the legs 3 diverge slightly downwardly from the bottom 3 of the body 1 and co-operate with said bottom to form the top and side walls of the chamber 2. With this construction, a substantially fiat cover 4 is used to close the open upper end of the brine chamber 1 and is rigidly and permanently secured in place after the usual expansion coils (not shown) are positioned in the brine chamber. As shown, this cover 4 has a small fill opening 5 for the brine and has twp relatively large openings 6 and 7 respectively for receiving the inlet and outlet fittings (not shown) of the expan sion coils just referred to.

In the present instance the brine tank including the cover 4 is preferably formed of vitreous material which is glazed wherever desirable to produce a neat appearance. In the process of construction, the brine chamber 1 including the hollow leg portions 3 are formed in one mold, while the shelf 8 constituting the bottom of the chamber 2, and the cover 4 for the brine chamber are formed separately from the brine chamber and are secured thereto by separate operations. For instance, the shelf 8 is formed in a suitable mold and is then baked in the proper position between the leg portions 3 of the brine chamber to provide an integral construction, while the cover 4 is formed in a suitable mold and is then cemented to the upper end of the brine chamber. If desired, the inner cham ber 2 may be provided with two or more shelves 8 that may be formed and secured in position similar to the one shown.

Thus, from the foregoing description, it will be readily apparent that I have provided a neat and durable brine tank that may be constructed at a comparatively low cost. Inasmuch as the inner walls 2 of the hollow leg portions 8 diverge downwardly from the bottom wall 3 of the hollow body 1 and the shelf 8 and cover 4 are formed separately and are subsequently secured in place, it will also be apparent that the brine chamber 1 may be readily formed in and withdrawn from a very simple type of mold. Likewise the shelf 8 and the cover 4 may be readily formed in separate molds and may be easily secured to the brine chamber. Inasmuch as this tank is formed of vitreous material, it will also be apparent that it is not readily responsive to temperature variations, particularly when the doors of the refrigerator cabinet in which it is located are opened. Thus, a very efficient construction is provided.

While it is believed that from the foregoing description, the nature and advantage of my invention will be readily apparent, I

desire to have it understood that I do not limit myself to what is herein shown and delUO scribed and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What I claim as my invention is:

1. A brine tank formed entirely of vitreous material and comprising an open top chamber for brine, a cover for the open chamber, and a shelf of vitreous material integral ly connected to portions of said chamber and forming therewith a compartment for receiv= ing trays in which ice may be formed.

2. A brine tank formed of vitreous material having a chamber for brine, said chamber having spaced leg portions, the op posed inner walls of said leg portions diverging downwardly, and a shelf of itreous material integrally connected to said diverging walls.

3. A brine tank formed entirely of vitreous material and comprising a hollow open top body provided at its opposite ends with depending hollow upwardly opening leg portions, and a shelf extending between said leg portions and forming therewith a comp'ai'tment for receiving trays in which ice may be formed.

4. A brine tank formed entirely of vitreous material and comprising a hollow body having laterally spaced depending hollow leg portions openii'ig into said hollow body, and a shelf of vitreous material disposed between said leg portions and having its side edges integrally connected to the opposite inner walls of said leg portions and forming therewith a compartment for receiving trays iii which ice may be formed.

In testimony whereof I afiiir my signature.
